UNITED ST TE JAMES C. GARNER, OF HOUSTON, TEXAS.

Application filed March 17, 1919. Serial No. 283,203.

To all whom it may concern:

Be it known that JAMES C. GARNER, a citizen ot' the United States,residing at Houston, in the county of Harris and State of Texas, hasinvented certain new and useful Improvements in a Gin, of which thefollowing is a specification.

This invention relates to new and useful improvements in a gin, and hasmore particular relation to a ,gin for cotton and other similar fibrousmaterial.

One object of the invention is to provide a machine of the characterdescribed, which has been specially designed for the purpose ofseparating lint cotton from the cotton seed and also for separating thebolls, stems, leaves, motes and other foreign matter from the lint, andfor collecting said lint and foreign matter separately, and dischargingthem separately from the gin.

Another object of the invention resides in the provision of an improvedform of roll box, wherein the seed cotton is collected and held withinthe range of the Saws, to be operated upon by saidsaws for the purposeof stripping the lint from the seed.

A further feature of the invention resides in the provision of means forcleaning the lint, after it hasbeen separated from the seed, from thegin saws, said separating means including an air blast nozzle, throughwhich an air blast is discharged against the saws, and a suction nozzlethrough which an air suction is created to collect the lint from thesaws and deliver it into a lint flue through which it is delivered tothe con denser.

A still further feature of the invention resides in the provision of animproved form of air inlet pipe and blast nozzle, said pipe being somounted in the casing, that it may be revolved on its own axis so as tocarry the nozzle away from the saws, to permit access to the saws andnozzle for the purpose of inspecting and cleaning the same.

With the above and other objects in view, the invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an example of whichis given in this specificationand illustrated in the acompanying drawings, wherein:

Figure 1, is a front elevation of the gin shown partially in section,taken on the line 1-1 of. Figure 3.

Figu 2, is a r r'el ve ion th of; hown partially in section, taken onthe line 22 of Figure 3.

Figure is a transverse sectional view taken on the line 3-3 of Figure 1.

Figure 4, is an enlarged fragmentary sectional view taken on the line3-3 of Figure 1, and showing a fragmentary view of the saw, and the airblast nozzle in its relation thereto, and

Figure is an end view, shown partially in section.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, thenumerals 1, indicate the end plates of the casing which are provided tosupport the operative mechanism of the gin. Pivoted between said platesin the upper part of the casing in front, is a frame, consisting of theends 2, 2, suitably secured together, as hereinafter explained, andhaving its front side formed of the breast 2, which is hinged to theframe so as to be readily opened and closed, and at the rear of the gin,there is the shutter, 3, said shutter being hinged between the endplates 1, 1, so as to be readily opened to permit access to the interiorparts, from the rear. The numeral 4, refers to a transverse shaft whichis rotatably mounted in suitable bearings 5, which are carried by theends of the casing, and fixed upon this shaft are the circular gin saws6, which are spaced a uniform distance apart on said shaft by means ofthe annular spacers 7, interposed between the saws. These saws aresuitably serrated, so as to engage with the lint and strip the same fromthe seed. Rotation is imparted to the shaft 4, and the saws through asuitable pulley 8,. which is fixed upon one end of said shaft.

Transversely disposed in front of the saws and beneath them is thepicker roller 9, which is fixed upon the shaft 10, rotatably mounted endbearings 10, 10, carried by the respective ends 2, Q, and said rollerhas spikes 11 projecting out from its periphery. Behind the pickerroller there is arranged a plurality of huller ribs 1:2, whose lowerends are secured to the transverse bar 13, and whose upper ends aresecured to the transverse bar 14, said bars serving to connect the frameends 2, 2. These huller ribs are arranged to alternate with the saws,and are spaced a sufficient distance apart to permit the lint and seedsto pass between them, but they arrest all bolls, stems, leaves,

1 seed cotton collects in and other foreign matter which may be in thecotton, and prevent the passage of this foreign matter into the rollbox, hereinafter described. The seed cotton passes down behind thehuller breast a-nd is engaged by the spikes of the picker roller and bythem. carried into engagement with the saws, and the seed cotton iscarried said saws through between the ribs 12 into the roll box, but theforeign matter is arrested by said ribs, and drops down onto the pickerroller, and is by it, discharged down onto the seed board 15. However,the free ends of the spikes 1.1 are retracted, or bent back, so as toreadilyrelease the cotton and not to carry any. part thereof around outof range of the saws, Spaced behind the huller ribs 12, are the stripperribs 16, whose lower ends are secured to the transverse bar 17, andwhose upper ends are secured to the transverse bar 13, said bars 17 and18, being secured at their respective ends to the frame, ends2, 2, andsecuring said ends of said frame in fixed position relative to eachother. These stripper ribs are arranged alternately with respect to thesaw 6, and are closely spaced to prevent the passage of seed throughbetween them, but they permit the passage of the lint cotton, motes, andother small particles. The upper ends of these ribs are extended, andarcuate in form, forming the back side of the roll box, which is smoothand free of lint-engaging projections, and the'opposite side of saidroll box is formed by the rollbox-breast 19, which isarcuate in crosssection, and whose upper edge is swung from the transverse rod 20, thelower ed e of this breast resting upon the bar 14.. The roll box breast19, and the opposing ends of the stripper ribs 16, are oppositelycurved, so as to form between them, a substantially cylindrical rollbox, with-smooth interior walls, in which the a mass, and through whichthe saws 6, pass as they rotate, These saws pass through the cotton insaid roll box, and engage with the lint thereof, and cause the mass ofcotton in said box to rotate with a constant rotary movement, therebycoming constantly into contact with said saws which strip the lint fromthe seed, said lint passing through between the strip per ribs, but theseed being arrested thereby, and when freed, from the lint, graduallyworking from the roll and dropping onto the retaining board 31, andpassing thence down between the ribs 12. and 16, onto the seed board 15.The retaining board 31, is secured to the transverse shaft 32, which isrotatably mounted in suitable bearings in the frame ends 2. 2, and thefree edge of said board is slotted, forming fingers which are spaced auniform distance apart, and which project between the respective saws 6.One end cf the shaft 32 has the handle 33, fixed thereon, through whichthe angle of said retaining board may be adjusted, so as to retain theseed the required length of time until all of the lint is strippedtherefrom.' The seed board 15 is fixed to a centrally located shaft 21,whose respective ends have bearings in the end plates 1, 1, of thecasing. When the said board declines forwardly, as shown "in full linesin Figure 3, it will deflect the seed and, other foreign matter outtoward the front of the gin, but it'may be turned in the position shownin dotted lines in Figure 3, and it will then deflect the seed and otherforeign matter a.

and through which an air blastisdischarged downwardly against the sawsto blow the lint cotton therefrom. 'This air blast has the effect ofseparating the lint into a loose mass. The pipe 23 is, mountedinbearings in the end plates 1, 1, and is capable of partial rotationtherein,so that said pipemay be rotated on its own axisin the directionshown by the arrow in Figure 1, thus withdrawing the nozzle 24 from thesaws. Provision is thus made for gaining access to the saws and nozzlewhen it is desired to clean or inspect the same Supported by the endplates 1., 1, and arranged underneath the pipe 23, is a suction lintflue 25, formed with an elongated suction nozzle 26, which extends thefull length of the saws, and which is. arranged underneath and in frontofthe-air blast nozzle 24. The rear wall of this nozzle is extended,forming the apron 2.6, which is arcuate in form, and which extends uparound the saws, to the nozzle 24, forming a support for said lastmentioned nozzle. The lint cotton freed from the saws by the blastissuing from the nozzle 24 is collected by the suction nozzle 26, andcarried through it into the lint flue 25, and is carried thence to thecondenser. This suction nozzle also collects all loosetibre blown outfrom the mass of lint by the air blast nozzle 24, and which wouldotherwise-pass out into the air and be wasted. I am awarethat an airblast has heretofore been used to clean the lint cotleaves said nozzlepassinginbetweensaid saws and a part passlng outbeyond and missing. t esaws entirely thu m k ng: it

[iii

difiicult to recollect the lint and causing a considerable amount of thefibre to be blown out into the open air and wasted. I am also aware thata suction nozzle has been heretofore employed in ginning, for thepurpose of cleaning the lint from the saws by suction, but when usedalone with the form of suction gin, commonly employed, it must be soconstructed to create a sufficiently strong current that it is liable tobecome clogged, and will also tend to compact the lint into dense lumpsor masses, but the combination of an air blast nozzle with a suctionnozzle has not heretofore been used for thus purpose, and thiscombination is particularly advantageous for the reason that the airblast will separate the lint into a loose uniform mass, and the suctionnozzle will then draw the lint so formed into the lint flue and willcollect the stray particles of fibre blown out by the blast nozzle. Bymeans of this combination, the saws will be completely cleaned of lint,all of which is collected into the lint flue in a loose, clean andevenly formed mass, and in proper condition to be delivered to thecondenser to be formed into a bat, preparatory to baling. Furthermorethe suction through the lint flue delivers the lint so rapidly that itdoes not become con gested in said flue, and if the lint should becomeignited, on account of friction of the saws, or from any other cause, asoften ha.p pens, there will only be a small amount of lint in the lintfine to burn, and the fire may be therefore more quickly extinguished.

As heretofore stated, the ribs 16 are spaced apart a suliicient distanceto permit motes and other small particles to pass between them. Theseparticles are thrown, by centrifugal force of the saws, from the lintand pass out over the air pipe 23, and are caught in the long transversehopper 27, arranged at the back side of the gin. This hopper has adelivery belt conveyer 28, which travels over the idler rollers 29, 29,and is driven by a suitable driving roller 30. This conveyer receivesthe particles delivered by said hopper and carries them from the gin toany suitable receptacle provided for them.

The frame hereinbefore referred to is pivotedly mounted in the casingthrough the medium of the transverse rear bar 34. The ends 2, 2, of theframe, as Well as, the stripper ribs 16, are fixed to this bar 34, andit is pivoted at its respective ends to the respective end plates 1, 1.Beneath the lower end of the frame, there is a transverse shaft 35,which has bearings in the respective end plates 1, 1, and a manual lever36, is fixed to one end of this shaft. Each end of the shaft isconnected to the lower part of the frame on each side by means of togglelevers, as 37. \Vhen the manual lever 36, is p ll d d wnwa dly, it Willoperate through said toggle levers to carry the lower end of the frameoutwardly, thus completely freeing the saws. This is often necessaryinasmuch as foreign objects often get into the roll box, and which mustbe removed, or when it is desired to stop the operation of the ginningin case of fire or for any other purpose. iVhen this frame is so swungout, the operation will cause a slack in the belt 37, through which thepicker roll 11 is driven, and this stops the delivery of cotton by saidroller.

TV hat I claim is:
